kristine johnson visits an historic, privately owned span frozen in time. >> have a nice day, okay? captioning sponsored by cbs this is the "cbs evening news." >> axelrod: good evening. i'm jim axelrod. this is our western edition. it was a stirring sight this morning. law enforcement officers from every part of the continent traveled to new york city, filling the streets and standing together outside the funeral service for n.y.p.d. officer rafael ramos. it has now been a week since ramos and officer wenjian liu were ambushed and killed by a gunman who posted threats to kill cops on social media. a week that has seen tensions spike in a city that was already embroiled in protest and debate over police and race relations when the two officers were killed. but, as mark albert reports, at the funeral today, there were calls to bridge the growing divide. >> reporter: in a grand procession of sorrow, a street-

wide line of blue, an estimated 25,000 officers strong, stood as one beside christ tabernacle church in queens. inside, a montage of officer rafael ramos' 40 years of life flashed by. he was killed the day he would have graduated as a chaplain leaving behind two sons. new york city police commissioner william bratton. >> know that we'll never let youd be alone again, that we are your family now. >> reporter: the family of wenjian liu, who was ambushed alongside officer ramos, inside the church to mourn alongside. vice president joe biden: >> so when an assassin's bullet targeted two officers, it targeted the city and it touched the soul of the entire nation. >> reporter: at the funeral, both men were promoted to detective, and ramos to honorary chaplain. in an appearance full of tension, new york city mayor bill de blasio, at odds with many in the rank and file, told the ramos family, "our hearts

are aching." >> officer ramos put his life on the line every day so other new yorkers could live in peace, so they could live in safety. that's what he believed in. >> reporter: during the mayor's 10-minute address, hundreds of officers listening here outside turned their back, a sign of disrespect for a mayor the police union accuses of not supporting the force and of having blood on his hands. commissioner bratton called for an end to division. >> if we can learn to see each other other then when we see each other, we'll heal. we'll heal as a department. we'll heal as a city. we'll heal as a country. and wouldn't that be the ultimate, the ultimate honor for officers ramos and liu, if their deaths helped us to all heal. >> reporter: the sea of blue outside the church had police officers from coast to coast. sergeant art lessmess is from san fernando, california.

>> it's a sad day for law enforcement, but it's a sad day for people as well because law enforcement represents the people. >> reporter: but even this vast show of support could only provide so much comfort to a 13- year-old son who held his father's uniform cap and a widow given a flag representing so much sacrifice and sorrow. mark albert, cbs news, new york. a >> axelrod: the oldest son of officer ramos arrived at the funeral wearing his father's police jacket. at the wake last night, justin ramos provided a moving tribute to his dad. >> he was my rock. he was a beacon of wisdom. he was my absolute best friend. dad, i'll miss you-- i'll miss you with every fiber of my being. w >> axelrod: justin ramos. in cleveland today, thousands of demonstrators rallied in support of cops. the so-called sea of blue

>> i am at awe of all the support for those that do a job that most of us are too afraid to do. >> reporter: for cbs news, bill safos, cleveland. >> axelrod: elsewhere today, there were protests for two unarmed men killed by police. in chicago, a rally was held for dontre hamilton, shot 14 times last april in milwaukee. while a crowd of 150 marched in brooklyn for akai gurley, killed in a darkened stairwell in a public housing project last month. internet service in north korea took another hit today, which happened as the dictatorship blamed the u.s. for internet outages earlier this week. a spokesman for kim jong-un took it a step further with a highly personal slur aimed at president obama.al here's carter evans. >> reporter: the report today from north korea's state-run news agency directly blames the united states for the country'sou internet outage saying, "the

u.s., with its big physical size, like little kids playing hide and seek without any shame, starting disturbing the internet operation of the country's major media." the report targets president obama, who last week specifically accused north korea of being behind the cyber attack on sony pictures. north korea's national defense commission claims the president forced sony to release "the interview," which depicts the fictional assassination of kim jong-un. a government spokesman went a step further saying, "obama always goes reckless in words and deeds like a monkey in a tropical forest." >> it's like the terrible twos for them, the name calling. >> reporter: steven laff is a cyber-security expert. while he says north korea may be diplomatically immature. >> they absolutely have the capability to do damage, and when a child has a gun, you really try to talk to them in a different way. >> reporter: laff says north

korea's has been engaged in0 cyberwarfare for 30 years, but its own online infrastructure is limited. according to a recent analysis of north korea's cyber capabilities by hewlett packard, the country didn't even have an outside connection to the internet until 2010. as for taking that system down-- >> when i heard the north koreans blame the united states, i thought that was plausible. >> reporter: the white house is not commenting. all that's public right now about the cyber war is the war of words. carter evans, cbs news, los angeles. >> axelrod: another apparently unrelated hacking incident is targeting some of sony's video game customers. the company's playstation network is experiencing disruptions for the third straight day. microsoft's x-box live is also reporting some troubles. a hacker group has claimed responsibility. large brawls broke out in several shopping malls across the country last night. police say this one near pittsburgh started after a flash mob was organized on social media.

more than 1,000 teenagers descended on the mall. meanwhile, on chicago's navy pier, a pregnant woman was hospitalized and five people were arrested after a large fight involving about 30 people. there were also skirmishes in sacramento and memphis. the incidents do not appear to be related. a top leader of the somali terror group al-shabaab has surrendered. zakariya ismail ahmed hersi, allegedly the group's finance chief is now in the custody of the somalis. the russian economy, already reeling from sanctions and falling oil prices is getting hit on another front. as debora patta reports, russians can add major credit card companies to their list of mounting challenges. >> there will likely be little festive cheer over russia's holiday break because plunging oil prices and the falling ruble have brought the economy to the brink of collapse. add to this, the u.s.-imposed

sanctions over russia's annexing of crimea, and it's going to be a long, cold winter for ordinary russians. as part of the sanctions, two of th the world's major credit card providers, mastercard and visa announced yesterday they are no longer offering services in crimea, which has left many russians unable to pay for festive goods this weekend. russian president vladimir putin bet his entire economy on oil and gas, but if oil remains below $60 a barrel, the russian economy will contract by a staggering 4% next year. and with the prices of goods andod food already soaring, the economy will continue to deteriorate, says investment consultant chris weafer. >> we are now in russia in that situation, where it's very much in survival mode. >> reporter: russia's financial crisis comes as the region remains unstable. although pro-russian separatists and the ukraine has begun an exchange of prisoners, peace talks between both sides have

been canceled, leaving an already-tenuous situation in greater uncertainty. debora patta, cbs news, london. >> axelrod: gas prices dropped again today to their lowest level in more than five years. the national average is now $2.30 a gallon. gas prices have dropped every day since september 25. that is 93 days in a row, the longest such stretch since the aaa began keeping records. former president george h.w. bush will remain in a houston hospital through the weekend. the 41st president, who is 90 years old, was admitted tuesday for shortness of breath, but a spokesman says the former president's condition has improved to the point that doctors are discussing dates for the president to go home. still ahead, it never rains and the sun never shines, but growing season never ends at this farm of the future. and a failed demolition leads to the leaning tower of crimea when the cbs evening news continues.
